    • Personal results may still be available on your phone.
  • It won't respond to "Hey Google" on your phone, but responds to it on shared devices.
  • It no longer recognises your face as Face Match is also removed from eligible devices.

Audio clips and photos you took to enrol in these services are deleted. It may take some time for this change to take effect. For some older devices, you may need another way to remove Voice Match.
